Re: efi: Error mapping PA 0x (if "NX bit" (aka "NX Mode") is disabled)

Hold on, *DISABLING* the NX mode breaks the efivars??
Can you boot and use the efivars when enabling them (or does that  just break the boot altoegether)?

Re: efi: Error mapping PA 0x (if "NX bit" (aka "NX Mode") is disabled)

Absolutely, YES!

Can you boot and use the efivars when enabling them (or does that  just break the boot altoegether)?

Yup, double(*) booting after NX Mode is enabled, everything is fine

(*)= fun thing, please have a look at what's happening in the sequence below:

1. @me: entering UEFI's Settings

2. @UEFI: disable NX Mode

3. @UEFI: press <F10> (Save & Exit)

4. @computer: reboots

5. @computer: loads GRUB's .efi

6. @GRUB: boots Arch

7. @Arch: the entire EFI ecosystem is broken / unavailable

8. @Arch: reboots

9. @UEFI: enable NX Mode

10. @UEFI: press <F10> (Save & Exit)

11. 4., 5., 6. steps

12. @Arch: USB ports are not available, unable to use keyboard

13. @ssh: rebooting Arch

14. @Arch(?),@computer(?): crashes, HDD (nVME) LED remains turned on fixed (NOT blinking)

15. @me: force reboot by pressing <RESET> button

16. @computer: enters POST in Safe Mode (I have to press <F1>)

17. @me: <F1>

18. @UEFI: NX Mode is still enabled, OK

19. @me: exit without saving, OK

20. 4., 5., 6. steps

21. @Arch: everything back to normal

22. @me: HOORAY!

23. @me: heads to Arch Foums asking for some more infos (and support)

What if you use a different OS (uefi shell bcfg might be enough) to see if the issue is limited to Linux.

Windows boots just fine.
Interesting: when performing Advanced Reboot (hold <SHIFT> while selecting RESTART from the Start Menu) I can select Reboot into UEFI Frmware, but this will NOT boot the computer into the UEFI Settings screen.

Debian, like Arch, has NO EFI environment.

Linux debian 6.1.0-15-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.1.66-1 (2023-12-09) x86_64 GNU/Linux

dmesg_debian
dmidecode_debian
efivars_empty_debian
journalctl_debian
uname_debian

Done another Arch test: upon re-enabling NX Mode, this time USB ports were working just fine and I went straight into Arch, OK.
